I was planning on using a wall wart as a power supply for a simple circuit. I was hoping to use a LM317T to vary the voltage and use my Pot as R2 to adjust. Problem is I don't know if what I have is a pot or a variable resistor. It has 3 prongs on it and the resistance I measure between the 2nd and 3rd pins is 10K.
If I'm insane, can someone maybe tell me what would work better? Wall wart outputs 24volts.
I haven't even thought about using capacitors with this as I'm not really building a full fledged power supply, just something that I can use to drive a computer fan on my desk to circulate some air and maybe just screw around with. What do you think?
